W. and W. McOnie
of Glasgow
1885 After the dissolution of the Partnership W. and A. M'Onie, Engineers and Millwrights, in Glasgow, the business in all its branches was carried on under the firm of W. and W. M'Onie, by William M'Onie, jun.[1]
1887 William McOnie, Junior died; his son (William McOnie (1877-1905)) was presumably left a large interest in the business but was too young to take over straight away.
1888 McOnie Harvey and Co was formed by the amalgamation of Harvey's and McOnie's. Robert Harvey Junior joined Sir Williams M'Onie as managing partner of Messrs. M'Onie, Harvey and Co.
1905 After the death of William McOnie, the firm became the Harvey Engineering Co., Glasgow.
